LeEco X800 Le 1 pro US SIM and IMEI lost

Hi.
I bricked my LeEco X800 Le 1 pro and when I recovered it doesn't recognizes sim and the IMEI number is 012345678901234.
The radio in Phone info is off and I cant turn it on.
Preferred network type can not be changed.
I tried to use QPST to change IMEI, but it does not connects fully.
Tried rom vresions:
Le1PRO_US_X800-ROW-PB-v60-CUOCO92-5.5.014S.zip
Le1PRO_US_X800-ROW-v48RL-CUOCO92-5.5.011S.zip
I used QFIL to unbrick my phone and then it had 8gb rom so i formatted phone.
Now everything is ok except IMEI and sim problem
Help!

I have the same problem. No imei. Phone does not detect Sim card.

There is already topic about this here http://forum.xda-developers.com/leeco-le1-pro/how-to/imei-lost-imei-letv-1-pro-x800-brik-t3430035
We need a QCN backup from working phone to solve this.

Please Try my QCN file from my working phone.
I used Qfil for backup.

The user "mariocolino" from Forum.le.com has confirmed that this QCN backup has fixed the signal problem.
I hope it will help other X800_us owner with the same problem to repair their phones.
Some helpful tools & files.

This worked for me to enter diagnostic mode.

I flash QCN, imei appeared but there is still no signal and no sound, what can i try.

Use this brush tool. => https://1drv.ms/u/s!AidiAJYxvGs2cPhtLogbcsqjYEo
It will get back all system defaults.
BUT WARNING!
It has a malware that installs apps itself.
After brush tool install custom ROM like cuoco92

if 4G doesnt work, try flashing the Non-HLOS from an x800 US image
Yoy can also see if you can activate the bands on the QCN file with QSPT

Note 7 null IMEI, need to write it back. Donation for sure.

Hello dear XDA users!
First of all I would like to give offer to one that will solve my problem, I will send him 30 EUR directly to his PayPal account.
I am Note 7 Lover as I am collector of these phones.
I have many succesful Note 7 phones recovered from death updates which were fully discharged.
But I did great mistake which I can´t live with.
I had one Note 7 , fully functioning with all connectivities. I managed to install HydraRom and Hydrakernel there on my own as I did it many times before. I am an idiot I didn´t make backup of the system and mainy EFS in working state.
I broke display a little on my primary Note 7 so I needed to recover my TWRP backup on another phone but I accidentally checked restore also EFS partion from my previous phone.
So the phone just turned on and No service, Baseband unknown. My great mistake.
Tried lots of original ROM restore, reflashing HydraRom or radios/kernels, nothing works.
I read a lot about what i did, I have no backup of EFS partion from the one that has problem. I have only Samsung Box with only IMEI written on it, back cover is changed so there is no IMEI or S/N.
I googled a lot, tried all the programs (Z3x, Chimera, Octopus) but none of them has capability to write IMEI directly to the this N930F phone.
I finally found a software called SAMFIX V1.3 and after clicking Baseband in the HydraRom phone menu is visible
The phone is able to look for carriers (but only one) but had NULL IMEI.
Wifi and Bluetooth works well, but there is no IMEI when i dial *#06# and imei is 0000000000. And Bonus is that the phone acts as Dual SIM, through it is only N930F single SIM. So the phone menu in HydraRom after dialing says 0000 for both IMEIs.
I tried to write IMEI with software IMEI changer via xposed, but it "writes" it only for the system instance.
Phone is still unable to find my carrier of connect to one.
When i tried to see device info with all softwares it says:
PDA Version: N930FXXU2BPJ8
Baseband Version: N930FXXU2BPI5
CSC Version: N930FOXM2BPI5
Please help me to restore EFS somehow, or at least to succesfully write IMEI and S/N (which i don´t really have) to phone and can connect to my network as before my idiosm I did with restoring ROM from "same" but different device.
Who will help me will get 30EUR from me (student) on his PayPal.

Did you tried stock firmware? If not flash N930FXXU3BPL2, and do wipe. https://forum.xda-developers.com/note-7/help/n930fxxu3bpl2-t3520988/page2

Hello!
I tried flashing oficial firmware, didn´t solve my problem, or something called COMBINATION Factory binary but this failed.
Radio and baseband is all OK, I have two other phones exactly with this firmwares and versions and they work all OK.
Problem is with EFS and CERT, before wrongly restoring this partion with TWRP backup from another NOTE 7 SM-N930F the phone worked all OK.
I managed to do with many softwares to write IMEI and S/N and it succeeded!
It is written in CERT file and not only with some IMEI changer for system run instance. It is readable via ADB.
Phone can unlock the SIM card but is unable to load carriers.
I read a lot of this problem and I compared CERT file of a backuped one and CERT on the restored one after my IMEI repair.
The CERT on the recovered one has it´s own IMEI now but has same ImeiSign,PubKey,PubKeySign as the backuped one from what I made restoration with TWRP.
So these codes are OK for the IMEI and S/N on the working one but they are inconert for the not working one because of encrypting.
I tried to flash CERT from the working one to bricked one but this does not work because of some CPID encrypting or so.
Have you please any solution to
1. Fully restore working EFS on the phone to work as before?
2. Try to make calculation for the right ImeiSign,PubKey,PubKeySign for that IMEI?

Redmi Note 5 AI baseband /imei problem - Need help

Hi,
I have a redmi note 5 AI/Global which I've had problems with - it's unable to get a signal with the sim card. It lost the imei numbers (and I'm assuming Baseband) with a TWRP restore where the user tried restoring the efs/modem partitions. The phone does pick up the network, but it doesn't show any reception. The sim card works fine in another phone.
I have:
1. flashed the baseband using the model's qcn using QPST
2. Changed the imei back to default using the imei change tool
It's currently on the latest dev rom. I'd really appreciate some help with it

try to search for qcn for the same model and restore it on your phone, it will work for sure

Redmi 5A Changing IMEI

I saw another post here asking pretty much the same question but I gotta ask again after trying every method I could find resulting in failure and frustration. Has anyone been able to change the IMEI numbers on a Redmi 5A? I tried both the Dual IMEI writer and QSPT even wiping out EFS partition and nothing worked. Can't even get IMEI to become a 0 with erasing modemst1 or modemst2. I think Redmi 5A's were the firsts of newer Redmi devices having newer security features as interestingly enough the phone won't boot after I changed the ROM from China to Global if I re-lock it, so I have to keep my bootloader unlocked.
If anyone could help me change the IMEI number I'd appreciate it so very much!
Thanks.
